A Preliminary Study on Age Determination and Examination of Some Growth Parameters in Agile frog (Rana dalmatina Bonaparte, 1839) (Anura: Ranidae) Specimens

Öz

In this study, a total of 16 Agile frog, Rana dalmatina species preserved in the ZDEU-COMU collection and collected from Çanakkale (4 ♂♂, 4 ♀♀) and Kırklareli (7♂♂, 1♀) were examined to estimate their age and the relationship between age and body size using the skeletochronology method. In addition, both femora and phalanx of the samples were evaluated together. Sexual maturity ages were found to be 2-3 in male and female individuals of both populations. The age ranges from 2-4 in males and 3-5 in females. According to this study, there was a positive correlation between length and age (r=0.740). In addition, no difference was observed in terms of LAG numbers compared to the age rings in the femora and Phalanx bones of the samples.

Çevik Kurbağa (Rana dalmatina Bonaparte,1839) (Anura: Ranidae) Örneklerinde Yaş Tayini ve Bazı Büyüme Parametrelerinin İncelenmesi Üzerine Bir Ön Çalışma

Öz

Bu çalışmada, ZDEU-ÇOMÜ koleksiyonunda bulunan Çevik kurbağa Rana dalmatina türüne ait toplam 16 örneğin iskelet kronolojisi yöntemi kullanılarak yaşları ve yaş ile vücut büyüklükleri arasındaki ilişkiler ortaya konmaya çalışılmıştır. Ayrıca örneklerin hem femur hem de falanj kemikleri birlikte değerlendirilmiştir. Eşeysel olgunluk yaşları her iki populasyonun erkek ve dişi bireylerinde 2-3 olarak bulunmuştur. İncelenen örneklerde yaş erkeklerde 2-4, dişilerde ise 3-5 arasında değişmektedir. Yapılan bu çalışmaya göre boy ile yaş arasında olumlu bir korelasyon olduğu görülmüştür (r=0.740). Ayrıca örneklerin femur ve falanj kemiklerindeki yaş halkaları karşılaştırıldığında LAG sayıları açısından bir farklılık gözlemlenmemiştir.
